探讨质子受体效应能够为电催化反应研究提供新的视角，本项目将重新探讨TEMPO及NHPI电氧化醇反应，研究电解液中质子受体对电催化反应的影响。电解液中质子受体包括吡啶及其衍生物、磷酸氢根离子、碳酸根离子、氢氧根离子等，包括循环伏安法、电解制备在内的电化学方法以及谱学技术将会用于评估不同种类及浓度质子受体对醇电催化的影响。本项目将仔细研究这些影响背后的理论依据，主要分析质子受体通过控制质子耦合电子转移步骤继而影响TEMPO及NHPI电氧化醇能力这种可能性。可以预计的是，本项目将有助于更全面地认识电催化反应中的电解液效应，同时也为基于质子耦合电子转移机理设计新的电催化体系打下坚实的基础。

By investigateing the so called “proton acceptor effect”, A new perspective can be provided in the studying of electrocatalytic reactions.In this project, alcohols electrooxidation by TEMPO and NHPI will be revisited, and effects of proton acceptors on these electrocatalytic reactions will be investigated. Proton acceptors in electrolytes include pyridine and its derivates, hydrogen phosphate ion, carbonate ion, hydroxyl ion and so on, effects of identity and concentration of proton acceptors on alcohols electrocatalytic activities will be evaluated by electrochemical technquies including cyclic voltammetry, preparative electrosynthesis and spectroscopy techniques. Theorectical basis behind these effects will be carefully studied，a possibility, that proton acceptors affect electrocatalytic abilties by controlling proton coupled electron transfer mechanism in TEMPO and NHPI mediated alcohol electrooxidation reactions, will be mainly investigated. It can be anticipated that this project will contribute to provide a more comprehensive understanding of “electrolyte effect” in electrocatalytic reactions, meanwhile, it will lay a solid foundation for the designing of new electrocatalytic systems based on proton coupled electron transfer mechanism.
